BACKGROUND OF THE INVENTION

1. Field of the invention

The present invention relates to a monitor support device with height adjusting function, more particularly one, which can be adapted to support various sizes of monitors, and which is equipped with a power source for adjusting the position of a monitor held thereon, and easy and convenient to use, and is used with a cabinet so that a monitor held thereon can be held in and protected from dust by the cabinet when not in use.

2. Brief Description of the Prior Art

Conventionally, a monitor is secured and supported on a support member that doesn't have height-changing function therefore the monitor can't be adjusted in height according to the user's need. And, a monitor will have shortened service life if it isn't protected from dust when not in use. Furthermore, conventionally the manufacturers have to manufacture various sizes of monitor supports because monitors come in various sizes. Therefore, it is difficult for monitor supports to be manufactured economically.

SUMMARY OF THE INVENTION

It is a main object of the invention to provide an improvement on a monitor support device to overcome the above-mentioned problem. The monitor support device of the present invention includes a first supporting unit, a power source, and upright and horizontal supporting units joined to the first supporting unit. The first supporting unit has an upright transmission screw passed through and threadedly engaged with the upright supporting unit such that the transmission screw will be turned, and the height of a monitor, which is held in place by the upright and the horizontal supporting units, will be changed when the power source is activated.

Furthermore, the first supporting unit is secured on a lowermost portion of a cabinet, which has a pivotal cover for an upper opening. Therefore, the monitor can be held in the cabinet and protected from dust when not in use; the upright supporting unit has pushing rods at an upper end for pushing and opening the pivotal cover when the monitor is moved upwards outside the cabinet.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIG. 1, a preferred embodiment of a monitor support device includes a horizontal connecting unit 5, an upright supporting unit 6, and a secured supporting unit 7.

The horizontal connecting unit 5 includes several horizontal connecting bars 51, each of which has a middle portion, left and right portions, several first connecting portions 510 spaced apart on the left and the right portions thereof, and two second connecting portions 511, which are between the middle portion and the left portion, and between the middle portion and the right portion respectively; the first connecting portions 510 can be through holes; the second connecting portions 511 have a hollow square shape, and each has a hole 512 on a lateral side thereof.

The upright supporting unit 6 includes two upright square rods 61, two propping parts 62, and a base 63. The upright square rods 61 are connected to two ends of the base 63 respectively at lower ends thereof. The propping parts 62 are joined to respective ones of lower portions of the upright square rods 61 for holding a monitor thereon, and the propping parts 62 can be loosened for relocation. The base 63 includes a hollow part 631, which is formed with internal threads. Furthermore, the base 63 has two lead holes 62 respectively formed on left and right ends thereof, two bearings 633 passed into respective ones of the lead holes 62, and a through hole 634.

The secured supporting unit 7 includes a base 71, left and right upright leading rods 72, a position-limiting stick 74, and an upright transmission screw 731. The upright leading rods 72 are securely connected to left and right ends of the base 71 respectively at lower ends thereof. The position-limiting stick 74 is connected to one of the upright leading rods 72 such that it is apart from and parallel to the upright leading rods 72. The upright transmission screw 731 is positioned between the upright leading rods 72 such that it can be turned around an axis thereof. Furthermore, a covering plate 75 is secured in front of the secured supporting unit 7.

Furthermore, a power source 73 is located on the base 71 of the secured supporting unit 7, and connected to a lower end of the upright transmission screw 731 such that the upright transmission screw 731 will turn when the power source 73 is activated. The power source 73 can be equipped with a stationary control or alternatively it can be equipped with a remote control.

In assembly, the horizontal connecting bars 51 of the horizontal connecting unit 5 are spaced apart, and securely connected to the upright square rods 61 of the upright supporting unit 6 by means of positioning the second connecting portions 511 thereof around the upright square rods 61, and passing screws 513 through the lateral holes 512 of the second connecting portions 511 to make the screws tightly pressed against the upright square rods 61. And, the upright supporting unit 6 and the secured supporting unit 7 are joined together by means of passing the upright leading rods 72 through respective ones of the bearings 633, and passing the position-limiting stick 74 through the through hole 634, and passing the upright transmission screw 731 through the hollow part 631 of the base 63 of the upright supporting unit 6 such that the upright transmission screw 731 and passed through and engaged with the hollow part 631, which is formed with internal threads. Thus, the horizontal connecting unit 5 and the upright supporting unit 6 together will be moved to a higher position when the power source 73 functions so as to make the upright transmission screw 731 turn in a first direction. And, the horizontal connecting unit 5 and the upright supporting unit 6 together will be moved to a lower position when the power source 73 functions so as to make the upright transmission screw 731 turn in a second direction.

A monitor is supported on the propping parts 62, and securely connected to the first connecting portions 510 of the horizontal connecting unit 5 at a rear side thereof; thus, the height of the monitor can be adjusted by means of activating the power source 73.

Referring to FIG. 5, each of the upright square rods 61 has a pushing rod 64 securely joined to an upper end thereof, and the secured supporting unit 7 is secured on an inner side of a bottom of a cabinet 8, which has a pivotal cover 81 on an opening of an upper end thereof. Thus, when the horizontal connecting unit 5 and the upright supporting unit 6 are moved to their lowermost position, the monitor and the whole support device will be completely held and protected in the cabinet 8. And, the pushing rods 64 on the top of the upright supporting unit 6 will push and open the pivotal cover 81 of the cabinet 8, and the monitor will move outside the cabinet 8 when the power source 73 functions so as to move the horizontal connecting unit 5 and the upright supporting unit 6 upwards, as shown in FIG. 5.

From the above description, it can be easily seen that the monitor support device has a simple structure, and it is steady, and easy and convenient to use.
